Seismic sources and neo-tectonics of Tehran area (North Iran)


This study records evidence of neo-tectonic activities in Tehran area. The aim of the study is to investigate the seismic sources in Tehran area and Mosha fault has introduced as the most active fault. The high seismicity potentials have appeared by integration of structural geology and active tectonics studies. Movement potential evaluation of the main faults in the current tectonic regime show that the North Tehran fault have 90% potential to movement. Also, geomorphic indexes indicate the presence of differential uplifting in the geological past. Recent activity of Tehran area is investigated by a large number of geomorphic indexes such as: drainage basin asymmetry, stream gradient. The stream network asymmetry was studied using morphometric measures of transverse topographic symmetry, asymmetry factor and drainage basin shape.
